Selena Gomez Had a 'Very Cute' Private Cheering Section for the Weeknd at His L.A. Concert

“She arrived right before he started performing,” an onlooker told PEOPLE of the singer, who hung out with a few friends in a VIP area at The Forum.

Added the onlooker: “Selena was dancing it up and singing along to all of The Weeknd’s songs, including his hit, ‘Starboy.’ ”

The 24-year-old, who rocked overalls and a black crop top (along with her new bob haircut), “seemed to be in great spirits,” shared the onlooker. “It looked like she was really enjoying the show and just having a good time.”

“They’re doing great together,” a Gomez source previously told PEOPLE. “Abel treats Selena really well and he makes her very happy.”

“They’re not shy about showing affection in public, and that’s not how she usually is,” said the source. “She’s pretty private about relationships, but she really likes him and doesn’t feel the need to hide it.”

Earlier this month, Gomez and The Weeknd were spotted packing on the PDA at Coachella in Indio, California. The couple was pictured getting cuddly while watching performances during the day, with Gomez nuzzling on her man’s neck as he wrapped his arm around her waist.

Gomez even shared a candid selfie of the pair while at the festival. The snap showed The Weeknd with his arm wrapped around Gomez’s neck, as she smiled subtly and held onto his arm. Both rocked sunglasses for the photo, with Gomez peaking out above hers.
